Vodacom Bad service

I have a complaint about Vodacom, this is by far the worst experience I have had. I have cellphone and a fibre contract with them and I was overcharged R583.25 on my March statement, I called the call centre to query what there was an extra charge on my account and no one could understand why, instead they said I skipped a month. I took them through all my payments and the team leader I spoke to (Lebo/Lesedi) not sure of her name, she confirmed there was a credit that was not processed therefore she will escalate it to the fibre department with a ref: SR ***,that was on 31/03/2021, I paid my normal amount end of the month of March since a credit was supposed to be done. To this day this has not been processed and it is on a pending status. Apparently Clint is still sitting with this credit note. My lines are currently suspended due to this. I am so frustrated and feel helpless because I have called so many time and sent emails but no one is helping or calling me back. I am working from home and this means I am unable to work without internet connection. Please intervene and help me with my complaint.

Thank you
